My wife and I are going to attend a symposium at Oxford University for a few days this September. The host is offering £205 on-campus accommodation for two nights. I'm not quite familiar with this place but I feel its a little bit expensive. The hotels nearby have a similar price level. I would like to know if this is indeed expensive and also what other options do I have.
In particular, as I have only experience with booking.com and not Airbnb, I could use some suggestion considering these two particular choices. booking.com's offerings range from £100+ to £4xx/night; Airbnb's offerings seem much cheaper (as low as £57/night).
